TO ALL WHOM IT MAY .CONCERNE Be it known that I, JOSEPH WALL, of the city, county, and State of New York, have invented a new' and improved Anti-Collision and Code Signal Lamp and I do hereby declare that the following is a. full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part oi' this specication, in which- Figure 1 is a front view of my invention. I

This invention relates to a newand improved anti-collision and code signal lamp, adapted for vessels at sea, to prevent collisions and afford a complete method of communicating information of any description between vessels at night. Y Y Y My improved lamp I construct of a. box, A, of block tin or sheet iron, about three feet four inches long, seven inches wide, and six inches deep. It is constructed with three openings aX aXAaX in front, having convex lenses tted in theln to throw the rays oi' light to a great distance. Within this box thus formed or'constrncted, I place threetubular cases B, which are fitted in circular apertures in the top of the box, and have three glass sections, red designated by a, green designated by b, and white designated. by c, and a dark or opaque section, d, (see iig. 5.) Within each of these cases a light is placed, and it will be seen, by turning these cases, a white, red, or green light, as desired, may be projected through the lenses in box A. The eases B may be retainedin position or prevented from turning casually by means of springs fitting or catching in notches the upper parts of the cases at the top of box-A. These cases B are turned by hand at the rear, of box A, and in' order that the operator may know how to-adjust or turn these ycases in order to throw the proper colored light out from the front of the box A, pieces of colored glass e are inserted in theupper parts of the cases B, at opposite sides to the corresponding colors, through which the rays of light aise projected from the cases, holesf being made in the rear of the box so thate may be seen.

From the above clescriptionit will be scenthat a white, red, or green lightmay be projected through either of the lenses of the box A, and eighteen diiferent signals or signs may be shown by various' combinations of'- the diiferentlights corresponding to t-hc diiferent flags used as day signals in the commercial'code of signals for all nations. The only difference between the day flag signals and my improvement is that oneilag represents one letter only. whereas in my invention each signal or sign represents aletter'and an important sentence attached, as shown `in iig. 6. The box A is placed upon a revolving stand or support C, so arranged that the device may be turned to face any point of' the compass and secured at any desired point. The upper partD of this stand, which revolves, has 'a disk, g, at,` its lower end, perforated all around near its edge with holes k, and this'disk Works over a corresponding perforated disk', i, on the stationary part E of the stand, a pin,` 7', passing through the holes in the disks to secure the revolving partD in position.

Having thus described my invention, I clainias new, and desire to secure by Letters Patent- The box A, having cases B tted in it, provided with dii'erentcolored glasses a, b c, and an opaque` or dark section d, and enclosing lamps 'or` lights, the cases being placed before openings in the box, and all arranged `substantially as and for the purpose specified.

I further claim the placing of the box A on a revolving stand, constructed and arranged substantially as and for the purpose set forth. i

The above specification of my invention signed by me this25thl day of October, 1866.
